Due to the unfreeable\npages, compaction fails.\n\nNeedless to say, at that point page reclaim also fails to create free\ncontiguous 2MB areas. However, that doesn\u0027t stop the current code from\ntrying, over and over again, and freeing a minimum of 4MB (2UL \u003c\u003c\nsc-\u003eorder pages) at every single invocation.\n\nThis resulted in my 12GB system having 2-3GB free memory, a corresponding\namount of used swap and very sluggish response times.\n\nThis can be avoided by having the direct reclaim code not reclaim from\nzones that already have plenty of free memory available for compaction.\n\nIf compaction still fails due to unmovable memory, doing additional\nreclaim will only hurt the system, not help.\n\n[jweiner@redhat.com: change comment to explain the order check]\nSigned-off-by: Rik van Riel \u003criel@redhat.com\u003e\nAcked-by: Johannes Weiner \u003cjweiner@redhat.com\u003e\nAcked-by: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nSigned-off-by: Johannes Weiner \u003cjweiner@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "21ee9f398be209ccbb62929d35961ca1ed48eec3", "tree": "4127e14f4a07a2cb7bc6eb902e9c7b0baab8e84f", "parents": [ "2f1da6421570d064a94e17190a4955c2df99794d" ], "author": { "name": "Minchan Kim", "email": "minchan.kim@gmail.com", "time": "Mon Oct 31 17:09:28 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 31 17:30:50 2011 -0700" }, "message": "vmscan: add barrier to prevent evictable page in unevictable list\n\nWhen a race between putback_lru_page() and shmem_lock with lock\u003d0 happens,\nprogrom execution order is as follows, but clear_bit in processor #1 could\nbe reordered right before spin_unlock of processor #1.

It, however, may access pages\nfield of vm_struct where a page was not allocated. This results in a null\npointer access and leads to a kernel panic.\n\nWhy this happens: In __vmalloc_node_range() called from vmalloc(), newly\nallocated vm_struct is added to vmlist at __get_vm_area_node() and then,\nsome fields of vm_struct such as nr_pages and pages are set at\n__vmalloc_area_node(). In other words, it is added to vmlist before it is\nfully initialized. At the same time, when the /proc/vmallocinfo is read,\nit accesses the pages field of vm_struct according to the nr_pages field\nat show_numa_info(). Thus, a null pointer access happens.\n\nThe patch adds the newly allocated vm_struct to the vmlist *after* it is\nfully initialized. So, it can avoid accessing the pages field with\nunallocated page when show_numa_info() is called.\n\nSigned-off-by: Mitsuo Hayasaka \u003cmitsuo.hayasaka.hu@hitachi.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Namhyung Kim \u003cnamhyung@gmail.com\u003e\nCc: \"Paul E.
